Release of version 1.5.

Enables ubh to automatically reconnect even when erroneous error codes are reported by the Net::Cmd Perl module.

Thanks to Frank Hofmann for working with me to resolve the problem. Thanks to Adam Rice for digging deep into the libnet modules to uncover the true problem, and for proposing a way for ubh to work around it.

Upgrading from any previous version to v1.5 is easy - just replace the executable. Your existing .ubhrc and .newsrc files are entirely forward compatible with v1.5.
